EAR-L B. STONER, OF ASTORIA, OREGON.

SPECIFICATION forming part of Letters Patent No. 741,736, dated October20, 1903.

Application filed September 9, 1902. Serial No. 122,738. (No model.)

To all whom it may concern:

Be it known that I, EARL B. STONER, a citizen of the United States, anda resident of Astoria, Glatsop county, State of Oregon,have invented anew and useful Improvement in Gas-Jet-Holder Attachments for Lamps of L-comotive-Headlights, of which the following I is a specification,reference being had to the accompanying drawings as a part thereof.

.The object of my invention is to provide an, attachment for theordinary oil-burning lamp of so-called locomotive-headlights'for thepurpose of converting the same into an acetylene-burner, at the sametime leaving the oil-lamp in such condition that in case of an emergencymy attachment may be readily removed, the oil-burner put back in place,and the lamp used as before.

I attain my object by the device illustrated in the accompanyingdrawings, in which Figure 1 is an elevation of the headlight on alocomotive, parts being broken away to show my attachment in place. Fig.2 is an elevation of the usual oil-lamp body of a headlight, partly insection and my attachment being operatively applied. Fig. 3 is anelevation of a like lamp provided with my attachment and illustrates theuse of a clamp as an additional means for securingm'y attachment inplace. Fig. 4 is a partial elevation like Fig. 2, showing a modificationin been removed.

My attachment consists of a jet or burner e, which is verticallyadjustable in the apertured cover or plate t', so as to bring the flamewithin the focal center of the reflector. From the base of the burner eprojects downward a stem Z, inserted in the socket m in which ordinarilyis inserted thestem or pin of the deflector-plate. The upper part of theburner e has a cavity, and it is adaptedto receive the gas-tip f and thedischarge end of functionates to vertically adjust the burner e, asmentioned. To this end such burner is provided with an exterior thread,and the aperture of the plate 41 is correspondingly threaded. Thus byturning the plate din eitherdirection the burner is raised or lowered. Aclamp j may be used for steadying the burner and holding the sameagainst being turned laterally by vibratory motion. A plan of such clampis shown in Fig. 5. The part j is inserted on the gas-pipe g, and by thethumb-screw k the clamp is secured in place. The described means foradjusting the burner e are deemed preferable over others. Thethread ofthe adjusting parts may, however, be omitted, as illustrated by e and71' in Fig. 4. The burner e merely slides up and down in the aperture ofthe plate i, and it is secured in place as adjusted by means of a clampj. The receiving end of the gas-pipe is connected with thegas-gencrating apparatus by a rubber tube It.

Having fully described my invention, what I claim, and desire to secureby Letters Patout, is-- 1. The combination with the lamp-body and thewick-case therein of a plate constituting a closure for the wick-case,and having a cen- 2. Thecombination'with thelamp-bodyand the wick-casetherein of a plate constituting aclosure for the wick-case, and having acentral aperture, a burner vertically adjustable in the aperture of saidplate, a gas-pipe entering the burner, and a clamp j for holding theburner in adjusted position, substantially as described.

The combination with thelamp-body,the wick-case and the socket, m,therein of a plate 1', constituting a closure for the wickcase andhaving a central, threaded aperture, a burner 6, provided with anexterior thread and vertically adjustable in said aperture of the plate2', a dependent stem or pin, Z, on and means for securing the burner inad- 10 the base of the burner, which stem is inserted justed position,substantially as described. in the socket m, and a gas-pipe entering theIn testimony whereof I have hereunto afburner, substantially asdescribed. fixed my signature, in the presence of two 5 4.
